Actually, Karl would be the first to point out that often spammers don't pay .. they hook up for their free trial period and get the boot a few days later.
Then companies need to look at wether free trial accounts should be able to send email. I think most trial are more useful to test connectivity, try the chat rooms etc. How many need email?
The whole point of spam being wrong is that since it is a cooperative process, it costs the recipient to receive it. (Contrast this to bulk postal mail, which only costs the sender anything.)
I would guess that the thousands (millions) of tonnes of junk mail cost us nothing to put into landfill sites, or incinerate... Matt. -- Matt Ryan - Network Engineer matt@planet.net.uk Planet OnLine Ltd, The White House, Tel: +44 113 2345566 Melbourne Street, Leeds, LS2 7PS, UK Fax: +44 113 2240003
